As liquid silicone applications continue to expand, manufacturers face increasingly specific requirements for material performance. Different products may call for different levels of flowability, tensile strength, tear resistance, elongation, transparency, and processing performance.
In many cases, problems such as poor surface feel, breakage during stretching, or unstable foaming performance are not caused by the production process alone. The choice of the right silicone base compound also plays a critical role in the final performance,and processing stability of liquid silicone products.
To cover different liquid silicone molding and production needs, Times Silicone has developed four core liquid silicone base products: BAS-1716, BAS-1841, BAS-1930, and BAS-1931.
From simple molding to high-performance, high-toughness, low-hardness, and foaming silicone products, these four base compounds provide distinct material options for liquid silicone manufacturers.
BAS-1716 Silicone Base: Excellent Flowability for Simple Molding
BAS-1716 is a precipitated silica-based silicone base compound with a viscosity of only 130,000 mPa·s. Its excellent flowability allows smoother processing and stable performance, making it well suited to simply molded silicone products while helping manufacturers keep material costs down.

For manufacturers looking for a practical base compound that balances processing performance and cost control, BAS-1716 is a solid choice for conventional liquid silicone applications.
BAS-1841 Silicone Base: A Versatile Base for Silicone Adhesives and Textile Printing
BAS-1841 is manufactured with fumed silica and positioned as a general-purpose liquid silicone base compound. It is primarily used for producing addition-cure liquid silicone adhesives and liquid silicone for textile screen printing, providing a versatile material option for different silicone processing applications.

For applications that need broad processing compatibility, BAS-1841 serves as a practical, all-around base compound for a range of liquid silicone products.
BAS-1930 Silicone Base: Balanced Mechanical Performance and High Transparency
For high-performance liquid silicone products, balanced mechanical properties often matter more than any single performance indicator. BAS-1930 is also manufactured with fumed silica. It delivers a balanced combination of tensile strength, tear resistance, and elongation, along with high transparency, making it suitable for applications where both mechanical performance and appearance are important.

For manufacturers looking for a high-performance base with balanced mechanical properties and good transparency, BAS-1930 offers a targeted material solution.
BAS-1931 Silicone Base: High Viscosity and High Toughness for Demanding Applications
For liquid silicone products that require high elongation, toughness, and low hardness, conventional base compounds may fall short. BAS-1931 features an ultra-high viscosity of up to 5,000,000 mPa·s and elongation of up to 550%, along with outstanding tear resistance. It is well suited to foaming liquid silicone and low-hardness liquid silicone products where flexibility, elongation, and toughness are key requirements.

How to Choose the Right Silicone Base Compound?
Different liquid silicone products require different material properties. Manufacturers can select the appropriate silicone base compound according to the product’s processing requirements and target performance.
| Silicone Base | Main Characteristics | Typical Applications |
|---|---|---|
| BAS-1716 | Precipitated silica, 130,000 mPa·s, excellent flowability | Simply molded silicone products |
| BAS-1841 | Fumed silica, general-purpose formulation | Liquid silicone adhesives, textile screen printing |
| BAS-1930 | High transparency and balanced mechanical properties | Liquid silicone adhesives, textile screen printing |
| BAS-1931 | 5,000,000 mPa·s, elongation up to 550% | Foaming liquid silicone, low-hardness liquid silicone products |
From simple molding to high-performance silicone applications, these four silicone base compounds cover different production requirements and provide manufacturers with more targeted material choices.
RoHS and REACH-SVHC Compliance for Export Applications
Material compliance is another key consideration for manufacturers serving international markets. All four Times Silicone core silicone base products comply with RoHS and REACH-SVHC export environmental requirements and are manufactured in line with applicable Chinese national testing standards.
For manufacturers serving overseas customers, material selection should take into account not only mechanical and processing performance, but also environmental compliance and export requirements.
Times Silicone: Silicone Base Solutions for Liquid Silicone Manufacturing
Choosing a silicone base compound is not simply about picking the material with the highest performance parameters. The right material should be matched to the product structure, processing method, hardness, transparency, tensile performance, tear resistance, elongation, and final application.
With BAS-1716, BAS-1841, BAS-1930, and BAS-1931, Times Silicone offers a range of liquid silicone base compounds designed for different production requirements, helping manufacturers reduce the need to stock numerous specialized base products and making material selection more efficient.
